Zercher? Wassat?

So, What is a Zercher Squat?

The Zercher squat was developed by Ed Zercher, a well-known powerlifter and strongman from St. Louis who competed back
in the ’30s. Rumor has it that Zercher’s home gym lacked a squat rack,
so he would load a barbell on the floor, squat in front of it, hold it
in the crook of his arms and lift the weight with his legs and lower
back.

Basically a combination deadlift and squat, the Zercher squat works the legs, glutes and lower back. Many lifters find it helps them get much better form on the squat; it’ll also help build strength in the bottom position where most athletes are typically weakest.
